Article Abstract:
The effects of artificial defoliation of pines in a mixed pine-spruce forest on the composition of the fungal community in a forest soil is determined using denaturing gradient gel electrophoresis (DGGE) and Biolog filamentous-fungus plates. The results indicate that combined genetic physiological assessments of the soil fungal community are needed to accurately access the effect of disturbance on indigenous microbial systems.

Article Abstract:
Efficient killing of nemotodes by Stropharia rugosoannulata Farlow ex Murrill cultures are observed. It is shown that the nematode-attacking activity of this fungus is carried out by these spiny acanthocytes and that mechanical force is an important factor in the process and the growth and nematode-attacking activity of the fungus in soil are also determined. Results suggest that acanthocytes are functional in soil.

Article Abstract:
The effects of long-term elevated atmospheric CO2 on root production and microbial activity, biomass, and diversity in a chaparral ecosystem in southern California are examined. The fungal biomass is correlated with cellulose and amylase activities, which indicates that fungi are responsible for the stimulation of enzymatic activity in the free air CO2 enrichment (FACE) treatment.
